Ch 14 CSF Flow Pattern Flashcards
The 4 ventricles that make up the brain are called:
-Lateral Ventricles (2)
-3rd Ventricle
-4th Ventricle
True or false: the 4 ventricles of the brain are called the parietal (2), 3rd, and 4th ventricles
FALSE,
LATERAL not parietal
A cavity existing in the interior of each _ hemisphere is why there are 2 lateral ventricles.
cerebral
The largest of the ventricles is/are the _ _.
lateral ventricles
The 2 lateral ventricles are separated by the _ _.
septum pellucidum
True or False: Each lateral ventricle communicates with the 4th ventricle via the Intervertebral foramen of Monro.
FALSE!!! Not 4th ventricle and not intervertebral!
3rd ventricle and Interventricular foramen of Monro
The 3rd ventricle is _ and is found between the _ of each side.
narrow, thalamus
The 3rd ventricle communicates with the _ _ via the cerebral aqueduct of sylvius
4th ventricle
The Cerebral Aqueduct of Sylvius is found in the _ and helps the 3rd and 4th ventricle communicate.
midbrain
The medulla and the pons both house the _ ventricle.
4th
The 4th ventricle is continuous with the central canal of the _ which is continuous with the central canal of the _ _.
medulla, spinal cord
The CSF made in the ventricles enters the _ _ via the 4th ventricle’s 1 medial and 2 lateral apertures.
subarachnoid space
The 4th ventricle’s CSF drains from the central canal of the medulla, central canal of the spinal cord into the subarachnoid space via its 1 _ and 2 _ _.
1 medial and 2 lateral apertures
The function of the choroid plexuses that line the ventricles is to _ _.
produce CSF
True or False: The entire ventricular system is lined with choroid plexuses which produce CSF
FALSE not all of it,
certain sites in the ventricles
True or false: CSF is a clear, yellow-tinged, acellular fluid similar to blood plasma
FALSE,
it is COLORLESS
3 functions of CSF:
-cushions and supports brain and spinal cord
-works as a lymphatic system
-works as an environment for neurons
Path of CSF: Starts from where it’s made in the 2 lateral ventricles by the _ _ and passes thru the _ _ of _…(1/8)
choroid plexus, interventricular foramen of monro
Path of CSF: Continues from the intervertebral foramen of monro and joins the _ produced by the _ ventricle…(2/8)
CSF, 3rd ventricle
Path of CSF: Continues from the joining of CSF from the 3rd ventricle and passes through the _ _ of _. (3/8)
cerebral aqueduct of sylvius
Path of CSF: Continues from the cerebral aqueduct of sylvius and joins the _ produces by the _ ventricle…(4/8)
CSF, 4th ventricle
Path of CSF: Continues from the joining of CSF from the 4th ventricle and passes through the _ of the 4th ventricle into the _ _. (5/8)
apertures, subarachnoid space
Path of CSF: Continues from the subarachnoid space traveling upward around the _ and downward around the _ _. (6/8)
brain, spinal cord
Path of CSF: After circulating, CSF eventually enters the arachnoid _ where it is reabsorbed then passes thru the _ _. (7/8)
granulations, lateral lacunae
Path of CSF: Continues from absorption by the arachnoid granulation thru the lateral lacunae, draining into the _ _ _ and finally into the _ system of the body. (8/8)
superior sagittal sinus, venous system
The starting point of the flow of CSF begins in the _ _which is found in the _ ventricle/s.
choroid plexus, lateral ventricles
The end point of the flow of CSF terminates at the _ system of the body.
venous system
The 3 apertures of the 4th ventricle are called:
-foramen of luschka (2)
-foramen of magendie
True or False: CSF from the 3rd Ventricle pass into the Cerebellar Aqueduct of Sylvia
FALSE-not cerebellar, not sylvia
-CEREBRAL aqueducts of SylvIUS
